Logistics and Real-time Operations
Operational applications supporting delivery workflows, HR processes, chat, and notifications.
Gaaubesi Logistics needed internal systems to run delivery operations and HR processes, alongside real-time communication so staff could coordinate without refreshing a page or waiting on email. Nitesh built the backend for these applications across delivery management, HR, and a real-time chat and notification layer.
- Delivery status needed to reach staff and relevant systems as it changed, not on a polling delay.
- HR and delivery-management tools were used daily by non-technical staff, so the backend had to support workflows that stayed predictable under normal operational load.
- Real-time features (chat, notifications) had to coexist with the same Django codebase serving conventional request/response traffic.
- Built scalable applications using Django and Python
- Developed delivery-management systems and HR portals
- Worked with cross-functional product teams to translate operational needs into backend features
- Implemented real-time chat and notifications using WebSockets
Standard delivery and HR workflows are served through Django views and PostgreSQL as conventional request/response applications. Real-time features run alongside this through a WebSocket layer, allowing delivery status changes and chat messages to be pushed to connected clients as they happen, with Redis used to support message brokering between server processes.
- Kept WebSocket-driven features (chat, notifications) as an addition to the existing Django application rather than a separate service, which kept deployment and data access simple for a small backend team.
- Used Redis as the layer that lets multiple server processes share real-time state, rather than assuming a single process handles all connections.
- Modeled delivery status as an explicit, auditable state machine so operational staff and downstream systems see consistent status values.
- Real-time features degrade to standard request/response behavior if a WebSocket connection drops, rather than losing the underlying data.
- Delivery and HR data is written through the same transactional database used by the rest of the application, avoiding a separate source of truth for real-time state.

- Python
- PostgreSQL
- WebSockets
- Redis
- Real-time features are easiest to reason about when they are treated as a delivery mechanism for state that already has a durable source of truth, not as the source of truth itself.
- Operational tools succeed on predictability: staff using delivery and HR systems daily benefit more from consistent behavior than from added functionality.
